使用XDebug从Docker Container进行远程调试不起作用 [英] Remote Debugging with XDebug from inside a Docker Container does not work

问题描述

我正在尝试设置一个对接的AMP环境，无法让远程调试器工作。我的设置如下：

我有一个运行mysql的数据库容器，它的工作方式就像一个魅力。我使用以下Dockerfile构建了一个Docker映像phpmysqli

  FROM php：apache 
 
 RUN docker -php-ext-install mysqli mbstring 
 
＃zend_extension = / usr / local / lib / php / extensions / no-debug-non-zts-20131226 / xdebug.so 
运行pecl安装xdebug 
 RUN echo'zend_extension = /usr/local/lib/php/extensions/no-debug-non-zts-20131226/xdebug.so'>>> /usr/local/etc/php/php.ini 
 RUN touch /usr/local/etc/php/conf.d/xdebug.ini; \ 
 echo xdebug.remote_enable = 1>> /usr/local/etc/php/conf.d/xdebug.ini; \ 
 echo xdebug.remote_autostart = 0>> /usr/local/etc/php/conf.d/xdebug.ini; \ 
 echo xdebug.remote_connect_back = 1>> /usr/local/etc/php/conf.d/xdebug.ini; \ 
 echo xdebug.remote_port = 9000>> /usr/local/etc/php/conf.d/xdebug.ini; \ 
 echo xdebug.remote_log = / tmp / php5-xdebug.log>> /usr/local/etc/php/conf.d/xdebug.ini; 
 
 RUN echo'date.timezone = Europe / Berlin'> /usr/local/etc/php/conf.d/date.ini 
  

我打电话给

  docker run --rm -ti --name web -p 127.0.0.1:8080:80 -v / path / to / projects： / var / www / html --link db：db phpmysqli 
  

此phpinfo分别为php -i显示xdebug 2.3.2已启动并正在运行。

接下来我在IntelliJ IDEA中设置了一个名为Docker的服务器，其中Host 127.0.0.1 ，Port 8080 和Debugger Xdebug。我在Docker运行语句中设置了类似于Volume映射的路径映射。

在 PHP-> Debug设置中，我检查了我使用的端口 9000 用于传入连接，我将接受外部连接，我不会忽略来自未注册服务器的连接。

之后，我创建了一个名为Docker的新的PHP远程调试配置。服务器是Docker，会话ID是 XDEBUG_IDEA 。

我可以在Container上调用PHP文件，我可以连接到db通过链接...但是由于某种原因，当我尝试启动调试会话时，没有任何事情发生。我尝试使用一个cookie（是的，我设置 XDEBUG_IDEA 作为xdebug帮助程序中的会话ID）。我尝试发送 XDEBUG_SESSION_START = XDEBUG_IDEA 作为 GET ...

<你可以聪明的人告诉我我错过了什么吗？

解决方案

您可以尝试使用此配置。 php-apache构建提供两种方法来编译和启用模块php。
使用 docker-php-ext-enable xdebug 设置正确的文件配置更好。

  FROM php：5.4-apache 
 
＃启用并配置xdebug 
运行pecl安装xdebug 
 RUN docker-php-ext-enable xdebug 
运行sed -i'1 a xdebug.remote_autostart = true'/usr/local/etc/php/conf.d/docker-php-ext-xdebug.ini 
运行sed -i'1 a xdebug .remote_mode = req'/usr/local/etc/php/conf.d/docker-php-ext-xdebug.ini 
运行sed -i'1 a xdebug.remote_handler = dbgp'/ usr / local / etc /php/conf.d/docker-php-ext-xdebug.ini 
运行sed -i'1 a xdebug.remote_connect_back = 1'/usr/local/etc/php/conf.d/docker-php- ext-xdebug.ini 
运行sed -i'1 a xdebug.remote_port = 9000'/usr/local/etc/php/conf.d/docker-php-ext-xdebug.ini 
运行sed -i'1 a xdebug.remote_host = 127.0.0.1'/usr/local/etc/php/conf.d/docker-php-ext-xdebug.ini 
运行sed -i'1 a xdebug.remote_enable = 1'/usr/local/etc/php/conf.d/docker-php-ext-xdebug.ini 
  

I'm trying to setup a dockered AMP environment and can't get the remote debugger working. My setup is as follows:

I have a database container running mysql which is working like a charm. I built a Docker image 'phpmysqli' with the following Dockerfile

FROM php:apache

RUN docker-php-ext-install mysqli mbstring

# zend_extension=/usr/local/lib/php/extensions/no-debug-non-zts-20131226/xdebug.so
RUN pecl install xdebug
RUN echo 'zend_extension = /usr/local/lib/php/extensions/no-debug-non-zts-20131226/xdebug.so' >> /usr/local/etc/php/php.ini
RUN touch /usr/local/etc/php/conf.d/xdebug.ini; \
    echo xdebug.remote_enable=1 >> /usr/local/etc/php/conf.d/xdebug.ini; \
    echo xdebug.remote_autostart=0 >> /usr/local/etc/php/conf.d/xdebug.ini; \
    echo xdebug.remote_connect_back=1 >> /usr/local/etc/php/conf.d/xdebug.ini; \
    echo xdebug.remote_port=9000 >> /usr/local/etc/php/conf.d/xdebug.ini; \
    echo xdebug.remote_log=/tmp/php5-xdebug.log >> /usr/local/etc/php/conf.d/xdebug.ini;

RUN echo 'date.timezone = Europe/Berlin' > /usr/local/etc/php/conf.d/date.ini

I call

docker run --rm -ti  --name web -p 127.0.0.1:8080:80 -v /path/to/projects:/var/www/html --link db:db  phpmysqli

After this phpinfo respectively php -i shows that xdebug 2.3.2 is up and running.

Next I setup a Server inside IntelliJ IDEA called 'Docker' with Host 127.0.0.1, Port 8080 and Debugger Xdebug. I setup the path mapping analogous to the Volume mapping in the docker run statement.

In the PHP->Debug settings I checked that I use port 9000 for incoming connections, that I will accept external connections and that I will not ignore connections from unregistered servers.

After this I created a new PHP Remote Debug Configuration called Docker, too. Server is Docker, session id is XDEBUG_IDEA.

I can call PHP files on the Container, I can connect to the db via the link... but for some reason nothing whatsoever happens when I try to start a debug session. I tried using a cookie (and yes, I set XDEBUG_IDEA as session id in xdebug helper). I tried sending XDEBUG_SESSION_START=XDEBUG_IDEA as GET...

Can you smart people out there tell me what I missed?

解决方案

You can try with this configuration. php-apache build provide two method to compile and enable module php. It's nicer to use docker-php-ext-enable xdebug to set correct file configuration.

FROM php:5.4-apache

# Enable and configure xdebug
RUN pecl install xdebug
RUN docker-php-ext-enable xdebug
RUN sed -i '1 a xdebug.remote_autostart=true' /usr/local/etc/php/conf.d/docker-php-ext-xdebug.ini
RUN sed -i '1 a xdebug.remote_mode=req' /usr/local/etc/php/conf.d/docker-php-ext-xdebug.ini
RUN sed -i '1 a xdebug.remote_handler=dbgp' /usr/local/etc/php/conf.d/docker-php-ext-xdebug.ini
RUN sed -i '1 a xdebug.remote_connect_back=1 ' /usr/local/etc/php/conf.d/docker-php-ext-xdebug.ini
RUN sed -i '1 a xdebug.remote_port=9000' /usr/local/etc/php/conf.d/docker-php-ext-xdebug.ini
RUN sed -i '1 a xdebug.remote_host=127.0.0.1' /usr/local/etc/php/conf.d/docker-php-ext-xdebug.ini
RUN sed -i '1 a xdebug.remote_enable=1' /usr/local/etc/php/conf.d/docker-php-ext-xdebug.ini
